MicroUSRP2Test

如何测试
USRP2

准备:

firmware: for 8051 in USB
controller, mostly writen as .c and .a51FPGA: for FPGA,
mostly writen as .v (it seems fpga only has SRAM inside, so it need to download
software for fpga every time)host: for PC, mostly writen
as .cc

/gr-usrp

driver for dauther board: mostly
writen as .py and .cc

/gnuradio-example/python/usrp

example for single usrp board: all
writen in .py

/gnuradio-example/python/multi-usrp

example for multi usrp boards: all
writen in .py

开始测试:

如何上电开始:

step1. before plug in USB cable,
open two terminal.step2. to see a real time display of
all log messages: tail -f /var/log/messages (to check the usb driver is
correctly installed)

如何停止及断电:

step1. stop the
program.step2. disconnect USB connection and power
off

how to test the transmitter and receiver for daughter
board?The antenna should be connect by Tx/Rx SMA but NOT Rx2! there is a
switch for Rx2 and the switch is off in default!The Tx and Rx can NOT be
connected directly by cable! need a attenuator about 40-50 dB!!

/gnuradio-examples/python/usrp/usrp_siggen.py and usrp_fft.py
to observe signal
